Ns4 Anti-Rust Coating H/Green 1 Litre Primer & Undercoat

A water-based anti-rust primer and undercoat designed for metal surfaces, including mild steel and galvanized iron. It helps stop existing rust in its tracks while forming a protective base coat to prevent new corrosion from forming.

Its quick drying formula supports fast recoat, while its adhesion and moisture-sealing action promote long-term rust protection on both new and aged metal. This 1 litre kit is suitable for treating bare or previously coated substrates, delivering a stable, ready-to-topcoat surface once cured.

Key benefits

• Neutralises rust and blocks further corrosion
• Moisture sealing for a drier, more durable finish
• Fast recoat capability for efficient project timelines

What to expect

Designed for metal surfaces that experience exposure to moisture and oxidation, the coating contributes a stable foundation for subsequent topcoats while maintaining a low odour profile during cure.
